A ternary blend of gasoline (90% octane no), alcohol (75% ethanol, 25% methanol) and benzole (75% benzene, 15% toluene and 10% xylene) is burned completely in 35% excess 0,. Analysis of the blend shows 70% gasoline, 15% benzole and 15% alcohol. Calculate the complete analysis of the exhaust gas. Density of isooctane is 0.918 and n heptane is 0.684 g/cc Solution: Octane no. is the percent by volume of isooctane in an isooctane - n heptane mixture with same knocking tendency as the fuel. Gasoline is a liquid fuel, so basis should be in terms of mass, say 100 kg. Take note that every percentages in liquid fuel is expressed in terms of mass (except the octane number w/c is in percent by volume). Gaseous fuels , stack gas, and air are all expressed in terms of % by mole.
